What is a ventricular rate?
The presence of a R wave, they are considered your heart rate and represents the ventricles contracting.
How often is the blood pressure checked during a stress test?
Before, every 2.5 minutes during, and after.
What is the treatment for idioventricular rhythms?
Atrophine, pacemakers, CPR
When preparing a patient for a Holter monitor, how many electrodes are attached?
5 or more
What is the cause of an agonal rhythm?
Dying patient
What is an atrial rate?
Counting the atrial activity by the presence of the P wave.
What is the main indication for a exercise stress test?
It is usually done to search for coronary artery disease.
Does Torsades de pointes have p waves?
yes or no
No
What should you NOT do with a Holter monitor?
Don't bathe or shower while wearing the monitor
What is the normal (inherent) rate of idioventricular rhythm?
20-40 beats per minute.
How do you calculate HR?
1. 1500 divided by the number of small boxes you've counted from one R to R.
2. 300 1500 divided by the number of large boxes you've counted from one R to R.
3. Count the number of R waves and it by 10 on a 6-second strip.
When should a stress test be fully completed?
When a patient has reached at least 85% of the achieved maximum heart rate.
What do pacer makers analyze?
Atria, ventricles, or both
